LGCKNG MECHMIIISM FUR BAG- FRAMES.

Application filed November rlhis invention relates, generally, to im.-provements in bag-trames; and, the present invention has :re-terence,more particularly, to fastening;` and locking mechanism Ot the 'typeemployed tor effecting; the retention ot' the hinged bag trame-sectionsin their closed relation by simultaneously producing the loclredengagement of the respectivev bag traine fixtures, such as the lockandthe several latch elements or end fasteners.

The present invention, therefore, has tor its principal object toprovide a simpler, as well as au edectively operating and a convenientlymanipulated mechanism of a character for simultaneously etfeetingn theoperation ot the frame-lock and the latch elements or end-fasteners tormaintainingr the :trainescctions in their closed relation, and to bereadily manipulated for expeditiously open inp; the hinged members otthe bag-trame.

The invention has for a further object to provide a fastening mechanismfor bagiframes, combining with the usual hinged trame-sections, a noveland positively acting basin-engaging means, actuated by an ar-Arangement` of connecting' slides or bars, which are actuatedsimultaneously with the operation ot the bag-lock mechanism, todisengage the hasp-engaging means from their normal holding or lockedeng-agement with an arrangement of auxiliary hasps or .latchmembers.

Other objects of the present invention not at this time moreparticularly enumerated will be more fully understood from thetollowingr detailed description of they present invention.

`With the various objects ot the present in vention in view, the saidinvention consists, primarily, in the novel bag-trame fastening' andlocking means hereinafter more :tully set forth; and, the inventionconsists, furthermore, in the novel arrangements and combinations of theseveral devices and parte, as wellas in the details of the constructionof the said parts, all of which, will be described in detail in thefollowing; speci-y ;dcation, and then linally embodied in the clauses otthe claims, which are appended to and which form an essential part ofthe specification.

rEhe invention is illustrated in the accompanying drawings, in whichFigure 1 is an elevation, showingr the in- 10, y1925. Serial N0. 68,099.

Figures 6 and 7 are views similar to F ig ures 1 and 2, respectively,illustratingV the frame-sections provided with a modified constructionof fastening or locking mechanism.

Figure 8 is a. longitudinal vertical section-y al representation, saidview being made on an enlarged scale; Figure 9 is a bottom view of themechanism represented in Figure 8, but shown detached from theframe-section; and Figure lOs a horizontal sectional representation,taken on line 10-10 in said Fig ure 8 looking in the direction of thearrows in said ligures.

Similar characters ot reference are employed in the above describedviews, to indicate corresponding parts.

Referring now to the several gures of the drawings, thereference-characters l and 2 indicate fragmentary porti-ons. ot. thehinged trame-sections of any of. the usual bagtrames., the frame-sectionl having suitably secured thereon, by means of lugs 4, or other suitablesecuring means, a bag-lock 3 of any suitable construction. In theVpresent case, the bag-loclr comprises a suitably shaped shell or casingas 5, adapted- 'to contain, any usual locking mechanism, which may beactuated by means of a lrey,4 the said shell or casing being shownsecured in this case upon the upper surface of the trame-section 1, bymeans ot the usual yend-lugs 4, as indicated in Figures 1, 2, 6 and 7 otthe drawings. Upon its upper face, the said shell or casing 5 hasassociated therewith a pair of openended box-shaped elem-ents, as 6,between which is disposed a suitably constructed keyreceiving element 7,for locking and unlocking the locking mechanism contained within theshell or casing 5, as may be desired. Movably disposed within eachbor-shaped element 6 is a slide S, each slide having a portion extendingfrom the open end of its respective box-shaped element, the Aproiectingportions of said slides 8 being prefer ably provided with manipulatingmeans, usually in the form of iingerpieces, as 9. Eirtending downwardlyfrom said slides 8, through properly located slits or openings in thetop of the shell or casing 5 and in the upper face of the frame-section1 are hasp engaging elements or posts, as 10, with the chamtered yedgeset which hasp-lugs 11, with which the frame-section 2 is provid-ed, areadapted to be brought into holding engagem-ent when the rame-sections 1and 2 are brought into the closed relation. The lockmechanism isprovided with suitably disposed springs 12, see Figure 2 of thedrawings, which constantly actupon and against the edges ot therespective hasp-engaging elements or posts 10, to maintain the saidelements or posts in their normal positions, shown in Figure 1 or' thedrawings.

Suitably secured upon the upper tace-portion of the trame-section 1,near its respective end-portions, by means of clamping lugs 13, or otherfastening means, are suitably shaped shells or casings 14, each shell orcasing resting directly upon a base-plate 15. The upper surface ot eachshell or casing 14 has suitably mounted thereon and secured in a fixedposition by means of a rivet 1G, or otherwise, a member 17 in imitationot the usual hinged or pivoted element of the usual bag-frame fastener.It will be understood, however, that these members 17, which in thiscase are used merely for ernamental purposes, may be entirely omitted,it desired.

Referring now more particularly to Figure 2 ot the drawings, it will beseen that the frame-section 1, beneath each base-plate 15, has an openportion 18, and that each baseplate 15, directly above each open portion1S, is formed with a correspondingly located opening 19. Suitablysecuredagainst the lower face of' each base-plate 15, by means of rivets 20, orother suitable fastening means, is a plate 21, each plate being providedwith a downwardly extending chambered member or box which is closed, asat 23, said closed portion, however, being provided with an opening 24,in alinement with the openg sseaaae ing 19 in the base-plate 15. Movablydisposed within each member or box 22 is a hasp-engaging lock-post 25,each post having an upper enlarged engaging end-portion 26, which isusually chamtered, as at 27, and which projects trom the opening 19 ofthe base-plate 15, as shown. The lower end-portion of each lock-post 25extends from the opening 24 of the chambered member or box 22, theprojecting end-portion of each post being slotted, as at 28. Within eachmember or box 22, each post 25 is encircled by a coiled spring 29, thepurpose of which is seltevident. Suitably secured to each plate 21 is abracket 30, with which is pivotally connected, by means of a pivot 31, acrank 32, each crank having a laterally extending iinger or arm 33,which in turn is pivotally connected by means of a pin 34, with theslotted or biturcated endportion 2G of' the respect-ive loek-post 25,substantially as show;z more particularly in Figure 4 of the drawings.Links 35 are employed for operatively connecting the respective hasp-lugengaging elements or posts 10 of the bag-lock with the crank-members 30of the respective endfasteners, by means of pivot-pins 36 and 37 at therespective ends of said links 35, as will be clearly evident from aninspection et Figures 1, 2 and 4 of the drawings. `he rame-section 2 isprovided in proper location with hasp-lugs or catches, as 38, and ot anysuitable construction, which are adapted to engage the cham'feredend-portions oA the respective lock-posts 25, when the frame section 2is closed wit-hin the frame-section 1.

The operation otl the mechanism for separating the various devices fromtheir locked or retaining engagement, when it is desired to bring thetraine-sections l and 2 into their open relation is simple, and isaccomplished by pressure upon the ingerpieces 9 of the slides 8 of themain bag-lock 3 in the directions ot the arrows 0s and y, indicated inFigure 1 of the drawings. The result is that the posts 10 of the lockare correspondingly moved in the directions of the said arrows, so as tobe withdrawn from the engagement with the hasps or catches 11. At thesame time, the links 35 actuate the crank-members 3G, which by means oftheir ingers or arms 31, actuate the respective lock-posts 25, which areconsequently drawn in downward directions, against the tensions of thesprings 29, so as to also withdraw the c-lianiilj'ered end-portions 26of the posts 25 from their locked or holding engagement with the haspsor catches 38, and whereby the frame-sections 1 and 2 are adapted to bebrought into their separated or opened relation, indicated in Figure 2of the drawings. he various springs 12 and 29 naturally return all theparts to their norma-l initial positions, when the pressure is removedfrom the finger-pieces 9. rllhe arrangementv andA construction of thevarious parts .ol'V the lock 3 and or" the fasteners at the ends of theirame is such, that when the trame-section 2 is closed Wit-hin theframasection l, the respective hasps or catches 'll and 58 will againreadily enter into locked or holding engagelnent with the respectiveposts l0 ot' the main loch 3, and with the posts 25 ot the respectivebag-frame fasteners located at the ends ot the trameeection l..

IOt course it will be understood, that the construction of the mechanismot the main bag-lool; E3 is such, so that when a hey is insorted in thelrejv-receiving` element 7, the mechanism within the shell or casing 5can be looked against movement, whereby the slides 3 and posts l0, asWell as the parts actuated from said posts, are also locked aga-instmovement.

in Vlieu of the particular construction of onddasteners herein-abovedescribed, and illustrated more particularly in Figures 3 and 4 oit thedrawings, l may enipl-oywith the form of main bag-'loclr and its postsl0 and lnlrs 35, end-fasteners 39 ot the construction illustrated inconnection with Fign uros 7, 8, 9 and l0 ot the drawings. ln thisinstance, each end-fastener comprises a shell or casing,` l0 securedupon the upper tace of the franse-section l by means of clamping lugs41, or other suitable :fastening means,

the u `3er surface or" each shell or casino' having suitably mountedthereon a member la in vimitation of the usual hinged or pivoted elementof the usual bag-'frame tastener. The upper surface of the said shell orcasing;` l@ is formed With a longitudinally extending` elongated opening43, said opening,` beingv made of a greater Width, as at Contiguous tosaid enlarged open portion flfl are a pair of lingers or lugs 45.Suitably mornted against the inner tace of the upper portion ot saidshell or casing; 40 is a plate 4 6 provid-ed `with an elongated openingfl?, longitudinally in alinement with the open portions i3 and i4 in thetop of the shell or casing 40.

The frame-section l in this oase isl also made at its end-portions Withelongated openings 48 in alinement with the openings 47, 43 and 4doi therespective endetasteners 39,- and slidably arranged in said openings ofthe respective fasteners are vertically disposed plates l-Q. Each plate49 is formed with a: downwardly projecting portion 50 and a laterallyextending finger 5l, each portion 50 having` a chamtered edge 52 forretaining or holding engagement with a hoolnshaped catch, as 53, withwhich the traine-section Q, is provided. Connected with each linger 5lof each plate 49, by means ot a rivet or pin all is a link 55, the' said.links being,` suit-ahh7 connected at their opposite end-portio`ns, bymeans of rivets or pins 56, with the respective posts l() of thebag-rame loch 3. 'fhat each plate i9 is properly maintained in its opertive position, Without interfering with its sliding nioveinent, eachplate is prroif'ided with a laterally extending pin 57 whi-cn bearsagainst the lower face of .the plate e6, and has its upper marginal edgebearing` directly upon the lower face of the n'iember L12. The normal'initial relation of the several parts i-s maintained by an arrangementor coiledv springs 6:0 bearing .against the marginal edges of therespective plates e9, each spring having its ends attached to the previ-Ously mentioned fastening lugs de, as will be clearii7 understood froman inspection of' Figures S and l0 ol the drawings. The construction andarrangement of the parts et the inain bag-loch 3 is the same as that,heretofore described in connection with Fig; ures l to 5 of thedrawings, and any :turther description of the saine is therefore deemedunnecessary.
